Looking for a fun, fast and relatively inexpensive brushless motor quadcopter? Then definitely check out the Whirlwind X251 from XK Hobbies!
This drone is well built with a carbon fiber frame, has 6 axis gyros for stability, brushless motors for speed and power, as well as three different flight modes that allow you to fly as tamely or aggressively as you want. Unlike the smaller toy drones that flip with a single button, this one uses the right stick control for flips, which is similar to have high end racers are designed to flip. I tried it out and found that I really like the way it flies as well as the price, just over $100 USD on GearBest.com. Here is the link to buy: http://goo.gl/W0mu8v
